Plasma process for coated fabric materials with Zinc to prepare antibacterial modal fabric

The textile technology of applying a Zinc oxide coating on Modal fabric is presented. The surface energy of the plasma treated fabrics was measured using contact angle measurements and showed a stabilization of this parameter with plasma of 3000 W min m−2. The plasma treatment induced negative charges on the surface of the fibers. The surface roughness measured by scanning electron microscopy (SEM) also showed stabilization with the same plasma dosage value. Inhibition of zone formation was studied via electron microscopy. Plasma treatment and ZnO coating improved the coating level of the samples and hence the conductivity of the fabrics was improved with the application. The fabric also showed slightly improved thermal stability yet a minor loss of strength was observed.
